' AERIAL APPARATUS;

A lication filed march '7, 1927. Serial no. 173,864.

This invention relates to an aerial appa ratus designed for use witharadio receivin set. It is of a type which may be containe within ahousing easily portable and installable at any desired point interiorlyof a building.

The present apparatusincorporates cer tain improvements in'the directionof siinplicity and compactness. It may conveniently be enclosed withinaprotective housing havinga location adjacent to or remote from, areceiving set. In addition','its antenna is comprised of a copper wirestrung back and forth between two head plates,and

therefor partly broken away;

Fig. 2 is a transverse section through the various wire stringings androds forming the antenna; 1 r s I Fig.- 3 is a fragmentary detail insection showing the mounting for one wireand rod; and

connection at one end of the antenna. The-present apparatus maycompr1sea base Aliavingupturnedmarginal edges 5 forming a shallow enclosure forthe recep v tion of the lower edges of a protective cover B having. abox-like structure. With the cover 'set', in place upon the base, acompletely protected compartment is provided. As by means of screws orhooks, not shown, the cover may be removably secured to the base. All oftheparts just described maybe made of any suitable material' finished asdesired.

Secured to the base in spaced-relation its several marginal edges, is ahorizontal plate 6 to the opposite ends of which are connectedupstanding headplates7 and 8 made preferablyfrom some insulated mate-Fig. 4.- which is a similar view showsthe.

rial. Each head plate is formed with a plurallty of aligned holes 9.and10, the latter being the larger. The hole. shown near the ,lower' leftcorner of the proximate head plate 7 in Fig. 1 is'of the larger size toaccommodatean eye'bolt 11 (see Fig. 4) which is desirably fastened inplace by nuts 12 which bear upon oppositesides of the head plate. Thebolt is disposed with its eye for convenient connection with one end ofa copper wire 14 which is extended to the other head plate 8. This wirepasses through an opening 9 therein in alignment with the eye bolt, and.then around upon the outer side of the head plate to an adjacent openingthrough-which it is strung back to the head plate 7.- In like mannerthis wire for its entire length is strung back provide amounting'therefor. s

In the form shown the wire stringings are located relatively close tothe edges of the head plates.- The endof the wire opposite to that whichis connected with the eye bolt may be joined to .a terminal 15 having-aneye through which is received one end of a conductor rod l6, preferablyof brass. These rods, of which several are shown,are all alike, as arealso their mountings in the two head plates. The ends of each rod 16, as

shown in Fig; 3, are'threaded to receive a pair of nuts 12 arranged ineach instance on- 0ppos1tesides of the proximate head thereuponwhen'suitably adjusted. In this mannerthe rods are secured againstmovement, as are also the head plates which form mountings therefor.

' 'As' each rod is an independent unit, Iprovide between them serialconnections adjacent outer sides of the two head plates. For.

'85 plate .and adapted to bear with pressure,

this purposeyl may employ link bars I? having. at their opposite endseyes which fit around the ends of the rods to be connected.

After the nuts 12 are tightened in place,

these link bars, :as well as the terminal '15,

are made secure so as to connect up in series the wire 14 as well as theseveral bars 16.

The construction thus-far described is one which provides anantenna-consisting of a continuous'wire strung back and forthbetwee'n'the two head plates in connection with 70 and forth between thetwo head plates which a plurality of bars interconnected in seriesfashion. One end of the antenna is constituted by the eye bolt which, bymeans of the associated nuts 12, is adjustable to take up slack in thewire. A flat copper bar 18 formed preferably with eyes at each end,connects this bolt with a binding post 19, the bar extending firstdownwardly from the bolt and then horizontally to the post which may bearranged adjacent one edge of the base A. A similar bar 20 havingconnection with a second binding post 21 extends also to the oppositeantenna end formed by one of the rods 16.

An aerial apparatus so constructed constitutes a unit which isconvenient for handling and installation, it being understood, ofcourse, that suitable conductors are to be extended from one of thebinding posts to the antenna connection of the receiving set, and thatanother connection, if desired, is to be extended from the other post tothe ground. In the exemplification shown, the parts forming the frame onwhich the an tenna is carried are of light construction withoutsacrifice of sturdiness. This is due in part to the character of the twoantenna components used, viz, the wire which tends to draw the two headplates together and the rods which serve to hold them apart. Inaddition, the arrangement by which the wires are grouped around the rodsis one which conduces to facility in assembly. This results from thefact that the frame can be completely set up and made rigid by the useof the rods alone after which the wire can be strung back and forthwithout requiring further support for the head plates. It is notnecessary, according to the construction shown, to resort to solderconnections at any point inasmuch as the several link bars may bepreformed to fit accurately in their intended plates.

In the operation of the present apparatus I have found that verysatisfactory results are obtainable. By'combining in an antenna a wirecomponent formed of copper strands in the usual way with a number ofconnected brass bars having a cross sectional size which is relativelylarge, I provide what is the equivalent of an aerial having a lengthconsiderably greater than the aggregate of the parts which are extendedbetween the two head plates. Also because of the fact that theconductivity of brass rods is slower than that of the copper strands,the flow of current is somewhat retarded, thus reducing to a largeextent the interference which normally results from static.
